NSA force CPU makers to limit CPU'S?

It just seems to me that multi-core processors are a waste, when that space could be better used by a single bigger processor core.

Anyone that's ever designed a circuit realizes that redundancy is redundant.  4 processors !/= 4x the power.  Fractional improvements are fractional of what normal should be.

With 32 bit float, you can get up to ~ +- 3*1038
With 64 bit float, you can get up to ~ +- 2*10308

Even if you convince me that 32 bit floats are insufficient, you can't convince me that 64 bit is insufficient; this latter range of numbers far exceeds the estimated # of particles in the universe.

Besides, 1038 + 1038 takes the same amount of time as 1 + 1: 1 clock cycle.

Good architectural design like efficient pipelining can dramatically speed up computation, but having extra bits won't.

The reason Crysis is slow on your shitty computer is because it's not fast enough, not because it's only 32/64 bit.  If it's a lack of precision, then numerical errors will corrupt the game's physics in no time.

Note to self: don't get RedCream angry.
